And according to The Sun, Mourinho has also set his sights on Roma midfielder Nainggolan.

He send scouts to watch both players and £85m-rated Saul Niguez during Roma’s 0-0 Champions League draw with Atletico earlier this month.

A United source told The Sun: “Jose sent scouts to the game to look at a number of players, but most importantly Nainggolan. He is a big fan of his. Griezmann was also looked at, but we know everything we need to about him already.

“They are going to go back in for him next summer, that’s for sure. The main thing is to replace Michael Carrick, though. Jose had wanted to sign Nainggolan as far back as his days at Chelsea, he is that big a fan.”

Peter Schmeichel on Phil Jones

06:10: Phil Jones is playing his best football at Manchester United.

That is the view of former Manchester United goalkeeper-turned-pundit Peter Schmeichel.

“I think this is Phil Jones’ seventh season at United,” Schmeichel told Sky Sports’ The Debate.

“He promised so much - United paid £18m and at the time, it was a staggering amount for a player like Jones.

“But he came in with this reputation of being so talented and at times we’ve seen that but then he gets injured.

“Balance and rhythm are two very important things in football.”

Marcus Rashford and Anthony Martial warnings

05:40: Manchester United must be careful not to unsettle Marcus Rashford and Anthony Martial in the wake of fresh speculation surrounding Antoine Griezmann’s potential arrival.

However, Nicol reckons United must not allow the latest speculation surrounding his potential arrival affect his players - in particularly Marcus Rashford and Anthony Martial.

Nicol told ESPN FC: “If you’ve got the money why don’t you go and get the best players?

“As far as Griezmann is concerned, he is a great player and he would make any team better regardless of who it is.

“The one thing United have to be careful about though, they’ve got two players in Rashford and Martial who you might unsettle with these sort of stories and this sort of information.”
